DESCRIPTION
The TK111xxM is a low dropout linear regulator with a builtin electronic switch. The internal switch can be controlled by TTL or CMOS logic levels. The device is in the “on” state when the control pin is pulled to a logic high level. An external capacitor can be connected to the noise bypass pin to lower the output noise level to 30 Vrms. An internal PNP pass transistor is used to achieve a low dropout voltage of 85 mV (typ.) at 30 mA l.
